As for Things of Process — or for Eternal Existents whose Act is not eternally invariable — we must hold that these are due to Cause; Causelessness is quite inadmissible; we can make no place here for unwarranted “slantings,” for sudden movement of bodies apart from any initiating power, for precipitate spurts in a soul with nothing to drive it into the new course of action. Such causelessness would bind the Soul under an even sterner compulsion, no longer master of itself, but at the mercy of movements apart from will and cause. Something willed — within itself or without — something desired, must lead it to action; without motive it can have no motion.

On the assumption that all happens by Cause, it is easy to discover the nearest determinants of any particular act or state and to trace it plainly to them.

The cause of a visit to the centre of affairs will be that one thinks it necessary to see some person or to receive a debt, or, in a word, that one has some definite motive or impulse confirmed by a judgement of expediency. Sometimes a condition may be referred to the arts, the recovery of health for instance to medical science and the doctor. Wealth has for its cause the discovery of a treasure or the receipt of a gift, or the earning of money by manual or intellectual labour. The child is traced to the father as its Cause and perhaps to a chain of favourable outside circumstances such as a particular diet or, more immediately, a special organic aptitude or a wife apt to childbirth.
